“E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight. Instead, we assess Dr. Doolittle’s testimony on a case-by-case basis as discussed below.” slip op. at 21

“B. Level of Ordinary Skill in the Art We consider the asserted ground of unpatentability in view of the understanding of a person of ordinary skill in the art (“POSITA” or “POSA”). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d Relying on the declaration testimony of its expert, Dr. Doolittle, Petitioner contends that an ordinarily skilled artisan for the ’678 patent “would have had an undergraduate degree (i.e., B.S., B.S.E. or the equivalent) in electrical engineering, materials science, physics, or a similar discipline” and “would also have one to two years of experience in the field of LED packaging design.” Pet. 5–6. Petitioner additionally contends that “[m]ore education could substitute for experience, and vice versa.” Id. Petitioner further contends that “[t]his person would have been capable of understanding and applying the teachings of the ’678 patent and the prior-art references discussed herein,” and “[m]oreover, the prior art reflects the level of skill at the time of the claimed invention.” Id. (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); Ex. 1102 ¶¶ 38–42). Patent Owner states that “solely for the purposes of this proceeding, Patent Owner and its technical expert employ the same level of skill in the art as Petitioners.” PO Resp. 24–25. Thus, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’678 patent and the asserted prior art, and we apply it in our obviousness analysis below.” slip op. at 10

“Cristofalo’s “user identifiers” represent data about users that Cristofalo’s system uses to “select a specific media object” (advertisements) from received “multi-object programming data.” Cristofalo at ¶ [0048]. For example, a user identifier may indicate that a given user is a Coca-Cola drinker, and when the receiving system receives the multi-object programming data it can select a particular media object out of several possible media objects (e.g., a Pepsi advertisement) to push to the user. Id. This user data exists independently of, and does not relate to, any particular media stream or streams. See Goodrich PO Resp. Decl. at ¶ 135. Petitioner seems to recognize this when tersely referring to “user identifiers” as “data,” not “data relating to a plurality of streams.” Pet. at 71.

We reproduce Petitioner’s arguments directed to claim 26 below: Rao’s policies 520 may “define prioritization” for network packets “based on whether an application is running in the foreground or the background.” [Ex. 1002] ¶ 182; id. ¶¶ 38–43, 180, 182, 188–89, 193, Figs. 5A, 5B. Each packet “may be placed and arranged in a priority order respective to all other . . . packets to provide a packet by packet prioritization across all applications 338a-338n and . . . network packets.” Id. ¶ 191. It would have been obvious to determine and apply a policy assigning a specific priority to packets associated with background applications, supra [1e]-[1f], and Rao thus discloses or renders obvious assigning a priority to network communications based on whether they are characterized as background services (class of services associated with application(s) running in the background of client 105), EX-1015 ¶¶195-96; supra [1e], [1f]. Pet. 33–34. Although the Petition sets forth why the claim limitation would have been obvious, there is no discussion as to how the additional limitation of claim 26—policy based on background class—is disclosed in Rao. See id. Similar arguments are presented for the other claims. See Pet. 30–31, 35–42. Because the Petition does not sufficiently show how the additional limitations recited in claims 20, 26, 58, 64, 165, and 169 were disclosed by Rao, Petitioner has not shown by a preponderance of the evidence that claims 20, 26, 58, 64, 165, and 169 were anticipated by Rao.” slip op. at 28

“Although Patent Owner points to various parts of the ’518 patent as supporting its proposal, other parts of the patent are not so limited. For example, the ’518 patent repeatedly mentions prior art patents disclosing communication techniques applied to twisted pair wiring, including discrete multi-tone (DMT) modulation and bit loading. Ex. 1001, 3:49–50, 3:67–4:2, 8:19–26. The patent further mentions that its data network overlays cable or satellite services. See, e.g., id. at 5:1–6. Thus, a POSITA would not be limited to experience only with “coaxial cables” as opposed to work involving signal processing and/or communication systems/networks more generally. The ’518 patent describes the “Technical Field” as “broadband communication networks and specifically . . . communications using coaxial cable building wiring.” Id. at 1:25–30. We find it appropriate here to use the broader statement of “broadband communication networks” as the field of a POSITA’s experience. The challenged claims of the ’518 patent relate to a “data communication network” comprising “cable wiring” with “segments of coaxial cable.” Id. at 12:16–19. This does not mean that the “cable wiring” is strictly coaxial—only that it includes segments that are.” slip op. at 11

“The ’518 patent seeks to overcome channel impairments by using probe messages to characterize the communication channel and determine optimum bit loading. Ex. 1001, code (57). These impairments include signal reflections, ISI, and signal attenuation. Pet. Reply 9–10 (citing Ex. 1001, 3:5–19). Similarly, Isaksson estimates channel characteristics by periodic transmission of a base sync frame from one transceiver to another where it is compared with a reference frame. Ex. 1013, 10. Isaksson’s channel characteristics may include attenuation, phase shifting, and variance, which are similar to the problems identified in the ’518 patent. Id. Both the ’518 patent and Isaksson address the problem of ISI by using bit loading to transmit data using sub-carriers less affected. Ex. 1001, 3:5–20; Ex. 1013, 16, 35, 79. Hence, we find the problems identified in the ’518 patent and Isaksson of how to overcome channel impairments reasonably pertinent such that Isaksson is analogous art to the ’518 patent. We find unavailing Patent Owner’s arguments that the ’518 patent is specific to in-home networks with coaxial cables and splitters whereas Isaksson is restricted to twisted pair, point-to-point networks having no intervening devices and which are located outside of homes. PO Resp. 15– 20; PO Sur-Reply 21–24. Any such differences do not change the fundamental nature of the problems of noise and interference affecting these environments. Such differences go more toward the field of endeavor than the reasonable pertinence of the problems each address. See Pet. Reply 10 (citing Donner Tech., LLC v. Pro Stage Gear, LLC, 979 F.3d 1353, 1360 (Fed. Cir. 2020)). Specifically, both the ’518 patent and Isaksson address the problem of channel impairments such as interference (e.g., ISI) and noise, and use the solution of bit loading to overcome them. See, e.g., Ex. 1001, 4:42–47; Ex. 1013, 1:3–7, 6:17–20, 16:10–16, 79:5–14. Hence, we find that the ’518 patent and Isaksson are analogous art because Isaksson is reasonably pertinent to the problems addressed in the ’518 patent notwithstanding Patent Owner’s arguments. We do not reach the question of whether the two are in the same field of endeavor.” slip op. at 17

“Kliger identifies the problems of splitter reflections causing inter- symbol interference, external noise, and dynamic network conditions adversely affecting home network communications. Pet. 23–24 (citing Ex. 1007 ¶ 73; Ex. 1010, 5; Ex. 1004 ¶¶ 65–68). Isaksson teaches using multi-carrier modulation, such as DMT and OFDM, to address frequency dependent loss and noise using synchronized bit-loading based on carrier SNR. Id. at 24 (citing Ex. 1004 ¶ 69; Ex. 1013, code (57), 26:4–20). We agree with Petitioner that the combination of Kliger and Isaksson amounts to the use of known techniques (Isaksson’s synchronized bit-loading) to improve similar devices in the same way (overcoming interference and maintaining connections with other modems). Id. at 26–27 (citing KSR, 550 U.S. at 415–421). We do not agree with Patent Owner’s argument that Kliger already solves the issues that Petitioner identifies such that a POSITA would not have looked to Isaksson’s synchronized bit-loading. PO Resp. 50. Petitioner has established that Isaksson’s solutions would improve Kliger’s modulation by determining the number of bits-per-carrier based on SNR, disabling noisy carriers, and synchronizing bit loading. Pet. 23–28; Pet. Reply 23–24. Hence, a POSITA would have been motivated to improve Kliger with Isaksson. See KSR, 550 U.S. at 417 (“if a technique has been used to improve one device, and a [POSITA] would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill”). Patent Owner alleges that Kliger’s network is coaxial whereas Isaksson’s is point-to-point, twisted pair with no intermediary devices such as splitters which would cause the interference, noise, and attenuation that the ’518 patent addresses. PO Resp. 50–55. However, we do not agree that these alleged differences would have precluded a POSITA from making the combination of references. “Signal impairments such as reflections, noise, attenuation, and inter-symbol interference (ISI) are common challenges in nearly all communication mediums.” Ex. 1036 ¶¶ 23–27. Communication networks experience these challenges, whether point-to-point or shared, twisted pair or coaxial, in-home or out-of-home, with or without splitters. Id. As Petitioner’s expert, Dr. Williams, puts it, “a POSITA can draw from the same toolbox of known solutions to address these impairments regardless of the medium.” Id. ¶ 27. Among those solutions is Isaksson’s approach of synchronized bit-loading. Moreover, Isaksson expressly states that “[i]t should be emphasized that the present invention can be used not only with the MUSIC system as herein described, but with other multi-carrier systems employing dynamic bit loading.” Ex. 1013, 72:5–8 (emphasis added); Ex. 1004 ¶¶ 81–82. Hence, a POSITA would have been led to consider using Isaksson’s synchronized bit-loading with Kliger’s coaxial network which uses a multi-tone transmitter to determine whether to transmit power on each particular tone. See, e.g., Ex. 1007 ¶ 166; Ex. 1013 1:1–7. Further facilitating the combination is Kliger’s disclosure of using “a regular multi-tone transmitter (either OFDM or DMT) to determine whether to transmit power on each particular tone wherein tones can be silenced (which is, in effect, a form of bit-loading). See, e.g., Ex. 1007 ¶¶ 6, 166, Fig. 1; Ex. 1013, 1:1–7, 3:24–34, 4:21–25, 16:8–12. In addition, Kliger expressly recognizes and seeks to address signal impairments caused by splitters, including poor signal isolation, return loss performance, degradation at higher frequencies, and inter-symbol interference due to reflections (the same problems the ’518 patent addresses). Ex. 1007 ¶¶ 61, 73. Accordingly, a POSITA would have been motivated to combine teachings of Kliger and Isaksson. Patent Owner argues that Petitioner did not explain how a control channel would exist across a coaxial splitter’s multipath signal. PO Resp. 56–58 (citing Pet. 26; Ex. 1013, 73:4–15, 74:22–31, Fig. 33; Ex. 2002 ¶¶ 147–148). Patent Owner does not explain why it would be necessary to use Isaksson’s control channel in Kliger, particularly when Kliger has its own control channel. Ex. 1007 ¶¶ 63–64, 166. Patent Owner’s argument amounts to bodily incorporation of Isaksson in Kliger, which is not a proper approach to obviousness. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). We further disagree with Patent Owner’s argument that Isaksson’s base sync frames (equivalent to the claimed probe messages) would not function in Kliger’s network. PO Resp. 58–60 (citing Pet. 26; Ex. 1007 ¶¶ 55–57; Ex. 1013, 24:8–28, Fig. 1; Ex. 2002 ¶¶ 149–154). Patent Owner’s arguments are directed toward an embodiment of Isaksson that Petitioner did not cite in its Petition. Pet. Reply 26. In any case, Patent Owner does not establish that using Isaksson’s base sync messages in Kliger’s system would have been beyond a POSITA’s skill. Id. at 25–26 (citing Ex. 1036 ¶¶ 90– 93). Patent Owner argues that Isaksson’s base sync frames would alter the principle of operation of Kliger because Kliger requires all devices to transmit fixed constellation size based on overall network characteristics rather than specific channel characteristics between each HNM. PO Resp. 60–63 (citing Ex. 1007, code (57), ¶¶ 40–44, 91, 99, Fig. 1; Ex. 1013, 3:24– 27, 20:24–25, 26:14–17, 78:5–79:5, Fig. 36; Ex. 2002 ¶¶ 155–157). Patent Owner has not established, however, that fixed constellation size is a “principle of operation” of Kliger, or that Kliger would require substantial reconstruction or redesign to incorporate variable constellation sizes. See In re Ratti, 270 F.2d 810, 813 (CCPA 1959). We agree with Dr. Williams that a POSITA would have sought to improve Kliger with Isaksson’s techniques. Ex. 1036 ¶ 95.” slip op. at 19
